Abstract

There is disclosed a laminate comprising (a) a layer of a styrenic polymer having a higher degree of syndiotactic configuration and a crystallinity of at least 25%, preferably 35%, (b) a layer of paper and optionally (c) an adhesive layer and (d) a barrier layer. The above laminate is excellent in heat resistance, hydrolytic resistance, tearability, dead foldability and gloss and can find a wide range of effective application. <IMAGE>
